Street Farbrengen Episode 40 - 19 Kislev - and the modern Heavenly Accusation

"That year, during Tishrei, the Rebbe was extremely joyful. He mentioned to the chassidim who were close to him that he had not yet made a seudas hoda'a for his geula, as one is obligated to do, al pi halachah. From this, they understood that the coming Yud-Tes Kislev would be something out of the ordinary.”What do I learn and use as a guide that the Alter Rebbe waited one full year to make a seudas hodaah, a thanksgiving meal? Street Farbrengen thinks of  a  current kitrig, heavenly accusation against Chassidus today and waits for a modern thanksgiving meal!
